Patent EP-0390872-A1 (EP)
Inventor: KAISER HANS-GERD
IPC: C11D7/14
Filed: 1989-01-24
Abstract: The invention allows cleaning of poorly accessible machine parts, e.g. in the transport and or moulding of materials in the pasty state by addition of one ore more inorganic or organic solvent(s) and one or more inorganic or organic salt(s) which are soluble therein, preferably as a solution, to the material to be processed. The melting point of the salt(s) is above the processing temperature of the material. The boiling point of the solvent(s) is below the processing temperature of tie material. The invention finds its application in the changeover of material to be processed in plastic processing machines, such as, injection moulding machines, extruders and blow-moulding equipment by accelerating the removal of the previous substance from the plasticizer unit and the nozzle region; an analogous field of use is, e.g. in the operation of kneaders.

Abstract: Lame en contact avec le sol, servant notamment pour les niveleuses de routes par abrasion, sur laquelle une plaquette de carbure est fixée par brasage au bord d'attaque de la pointe en acier. Les ensembles de lame de niveleuse, que l'on trouve dans le commerce, ont des plaquettes de carbure rectangulaires d'épaisseur égale, qui sont fixées par brasage au bord d'attaque de la pointe en acier. En raison de l'usure et des contraintes résiduelles exercées sur ladite plaquette de carbure pendant l'opération de brasage, celle-ci peut se fissurer et se casser prématurément. L'ensemble de la présente invention utilise une plaquette de carbure (14) ayant une arête tranchante plate de forme rectangulaire (30) mais d'épaisseur non constante, soudée par brasage au bord d'attaque (10) d'un corps en acier (12). Ladite plaquette de carbure (14) va en s'élargissant depuis le haut (25) de la plaquette (14) vers le bas (26) du corps en acier (12), où elle est la plus épaisse, l'usure de la lame étant la plus grande à cet endroit.

Abstract: In a release roller unit for open-ended spinning machines, the release roller is fixed in rotation with a shaft (2) projecting from and rotatable in a bearing box. The release roller (4, 8) projects beyond the bearing box (1) to form a hollow space (5) opening into an annular gap (6) limited by the bearing box (1) and the release roller (4, 8). To keep this hollow space clean at least one cleaning channel (10) extends from the hollow space to an end of the release roller obliquely to the roller axis so that an air flow forms in the cleaning channel (10) during the operation of the release roller unit.

Filed: 1990-05-07
Abstract: An electro-osmotic dewatering procedure is disclosed for removing water from saturated, porous building materials, such as concrete, brick and the like. A controlled, cyclical voltage is applied to an electrode system, to effect osmotic migration of water from an anode electrode (11), located within the structure or in contact with it, to a cathode electrode (13), typically spaced from the structure but in electrical circuit with it. The cycle of operations includes a first energy pulse in a direction (17) to effect osmotic migration, followed by a substantially shorter but definite pulse of reverse polarity (18) to prevent or minimize formation of insulating gas films and/or corrosion products. Transition from the primary pulse to the reverse pulse, and from the reverse pulse to the subsequent primary pulse, is at a controlled rate to permit discharge of stored voltage, as a function of inherent capacitance of the system, and to avoid generation of RFI radiations. For treating reinforced concrete, cycling is preferably controlled automatically, as a function of the monitored passivity or non-­passivity of the internal reinforcement, so as to avoid creation of corrosion products. Certain aspects of the invention are applicable to other treatments of reinforced concrete, such as realkalization.

Abstract: Until now, it has been normal to use cooling bodies for cooling electrical components and a printed-circuit board. The use of such separate cooling bodies and the fitment mean an increased production outlay which causes additional costs. In electrically insulating printed-circuit boards (1) which are integrally connected on their surface to projecting elements (2), it is intended to simplify the cooling of electrical components (4) arranged on the printed-circuit board. To this end, some of the elements (2), which are essentially of flat construction, have, for example, ribs, webs, metallised tracks and/or surfaces (3). These devices are used for dissipating and conducting away the heat losses from the electrical components (4) which are arranged on the printed-circuit board (1) and are in use. <IMAGE>

Abstract: A flexible package (7) for rescue equipment, specially adapted to be mounted on the exterior of a craft of the submarine type, the package being compressible around its contents so that it will take up a minimum volume. 
     The method of compressing the package is performed in a pressure vessel (1) containing fluid (5) into which the package is immersed. The package has a connection through a non-return valve (9) to a tube (8) communicating with the surrounding atmosphere. Pressurizing of the package takes place through a three-­way-valve (4), when the air contained in the package is expelled through the tube (8). On evacuation of the pressure vessel (1) the non-return valve (9) will close and the package (7) and its contents will remain in a compressed state.

Abstract: The method of this invention includes the step of providing a mandrel sleeve (18) shaped on the inside to fit over the small diameter end of a contoured container (12) and being of an outer diameter substantially equal to the large diameter portion of the container (12). After applying a solvent of the plastic sheet material to the trailing edge (10b) of a length thereof, the sheet (10) is wrapped around the container and the mandrel sleeve (18) so that the trailing edge (10b) overlaps the leading edge (10a) and the solvent forms a firm bond between the overlapped edges (10a,10b). The mandrel sleeve (18) is then withdrawn from the wrapped length, leaving it around the container (12) and the sheet material (10) is heat shrunk to fit tightly over its full height around the contoured container (12). Before the sheet (40) is wrapped around the mandrel (54) and container (42), an adhesive, such as a hot melt glue, may be applied to that portion (46) of the sheet (40) that is wrapped in direct contact with the container (42).

Abstract: Le dispositif électro-optique décrit contient un cristal liquide nématique chiral disposé entre des plaques planes traitées de façon à soutenir légèrement l'orientation moléculaire le long d'un sens préféré parallèle aux plaques. Les plaques sont espacées par une distance faible comparée aux pas de l'hélice typiques dans une masse du matériau ou de l'hélice compensée par des additifs pour assurer une situation équivalente. Grâce à l'application depuis l'extérieur d'un champ électrique, l'orientation moléculaire du cristal liquide est amenée à effectuer une rotation dans un plan parallèle aux plaques en s'éloignant de l'orientation préférée selon un angle dont le signe et la grandeur dépendent du signe et de l'amplitude du champ électrique. L'axe optique du cristal liquide, dirigé dans le sens de l'orientation moléculaire, est ainsi commandé par le champ électrique externe, de façon à permettre la création d'un relais optique linéaire ou autre dispositif électro-optique similaire.
